Hi Guys i need to pick your brains, i currently have an iphone but wanting to swap it for a Blackberry curve 8300 i am with 02 PAYG, and have been told if i stay with PAYG i wont be able to use the internet and wont be able to send picture messages either, unless i am on contract which i dont want to be!

If i buy a Unlocked/simfree 8300 will this still be the case? and is this problem with just o2 or is the same with other networks???
